« Last post by rolnor on Today at 12:43:47 AM »It seems natural to try a larger excess H2O2 and HCl? Do it in the cold.
While using HCl I received mostly monobrominated product, some significant part of substrate and little trace of something more unpolar (dibromo derivative?)
Try contacting Elutia. They make a TEA (Thermal Energy Analyzer) instrument. We used it to test for n- nitrosamines. It first came out under Thermo, but I think Ellutia bought it from them. The idea of the analyzer was to take the substances routed from a GC, pyrolyze them as they came out, then they were run through a could trap ( ours used EtOH and dry ice) and the left over gas went to the instrument. The Instrument took the gasses (NOx) and reacted it with O3( O2 came in and was exposed to an electric arc to make ozone). This chemoluminesced to produce red light which was measured. There were other steps, but you get the.idea. They might be able to help you.
